Description
Technical Field
The invention belongs to the technical field of diesel-electric hybrid cooling systems, and particularly relates to a high-compactness diesel-electric hybrid cooling system.
Background
Different from the traditional automobile which only cools the engine, the diesel-electric hybrid power system also needs to cool newly added parts such as a motor controller and a motor.
Compared with an engine, the inlet water temperature requirements of a motor controller and a motor of the diesel-electric hybrid power system are stricter; at the same time, the motor and motor controller have lower requirements for cooling water flow, and the average heat load is also lower compared to the heat load of the engine.
In order to solve the cooling and heat dissipation of the diesel-electric hybrid power system, a cooling system scheme of a high-temperature and low-temperature double-circulation loop is generally adopted, an engine system is cooled in a high-temperature circulation mode, and the low-temperature circulation mode is used for cooling newly added parts such as a motor controller and a motor. The high-low temperature double-circulation loop adopts two sets of water pumps, radiators and expansion water tanks, so that the overall structure is large in size and weight. Some research institutions also adopt a single-loop system, namely a motor controller, a motor and an engine are connected in series, and a water pump, a radiator, a fan and a radiating water tank are used for cooling and radiating, but the system can generate the phenomena of high-temperature and low-temperature heat channeling, incapability of controlling the water temperature of the motor and the like.
Disclosure of Invention
In view of this, the present invention is directed to a highly compact diesel-electric hybrid cooling system to meet the requirements of different cooling water flows of a motor controller, a motor and an engine.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a high-compactness diesel-electric hybrid power cooling system comprises a water pump, a tee joint, a one-way valve, a thermostat, a cylinder body radiator, a system radiator, a heat dissipation water tank, an air chamber and an air release valve,
the water outlet of the water pump is divided into two paths through a tee joint, one path is connected with a cooling system of a generator controller and a cooling system of a generator in series, the other path is connected with a one-way valve, and the two paths are connected in parallel and then connected with the cooling system of the engine body; one path of outlet of the cooling system of the engine body is connected with the cylinder body radiator, and the other path of outlet is connected with the system radiator through the thermostat;
the upper parts of the engine body and the system radiator are connected with a steam pipe, the steam pipe is connected with an air chamber, the air chamber is communicated with a heat dissipation water tank, and a release valve is arranged on the air chamber; and outlets of the cylinder body radiator, the system radiator and the radiating water tank are all connected with an inlet of a water pump.
Further, the heat dissipation water tank comprises a first-stage water tank and a second-stage water tank which are communicated through communicating holes, the second-stage water tank is composed of two water collecting chambers which are arranged from top to bottom and connected through a water pipe, fins are arranged on the periphery of the water pipe, a water replenishing pipe is arranged in the water collecting chamber located at the lower portion, and the water replenishing pipe is connected with an inlet of the water pump.
Compared with the prior art, the invention has the following advantages:
(1) because the heat load of the engine is great, the cooling water flow is also great, and the heat load of the electric machine controller and the electric machine is less, the cooling water flow is lower, so can not connect the electric machine controller, the electric machine, the engine directly in series, the scheme that this system adopted is: the water outlet of the water pump is divided into two paths through a three-way pipe, one path is connected with a motor controller and a motor, the other path is connected with a one-way valve, the two paths are connected in parallel, and the two paths of cooling water are supplied to the engine together to cool the engine. Therefore, the requirement of different cooling water flows of a motor controller, a motor and an engine can be met.
(2) The heat load of the generator controller and the generator in the system is not large in the working process, and only part of water of the water pump enters the generator controller and the generator, so that the water inlet temperature of the engine is not controlled due to the heat load of the motor controller and the generator. The water from the engine enters the radiator to be radiated, if the temperature of the engine is not very high, the thermostat is not opened, the water from the engine can enter the cylinder radiator in diameter and then flows back to the water pump, if the temperature of the water of the engine is very high, the thermostat is opened, and the water from the engine not only enters the cylinder radiator but also enters the system radiator. Because the water outlet of the engine flows into the water pump through the radiator, the water temperature entering the motor controller and the generator can be controlled.
(3) The high-pressure air release valve is positioned on the air chamber at the highest position of the diesel-electric hybrid power system, and when the pressure in the system is too high, the steam valve is opened, and steam and redundant gas in the system are released. The air chamber of the system is positioned between the radiator and the water tank. The high pressure bleed valve is not placed on the tank as in a conventional radiator, in order to allow the tank to be located lower so that the tank together with the radiator can dissipate heat by a common fan.
(4) The heat dissipation water tank mainly solves the problem of system water supplement, and because the heat load of an engine is large, especially when the engine is in high load, more high-temperature steam enters the water tank, the water of the heat dissipation water tank needs to be dissipated in order to prevent the water flowing out of the water tank from causing the water outlet temperature of a water pump to be overhigh. Different from the common automobile expansion water tank, the heat dissipation water tank has a lower installation position and also has a cooling function.
(5) The temperature requirement of the motor controller is higher than that of the motor, the heat load of the motor controller is relatively small, the temperature rise is low, the motor controller and the motor are connected in series in sequence, and therefore cooling water from the motor controller can meet the cooling requirement of the motor.

As shown in fig. 2, the radiator tank 10 includes a primary tank 13 and a secondary tank 14, the primary tank 13 is similar to a common expansion tank of an automobile, but has no high-pressure air release valve and a small air chamber; the primary water tank 13 is connected with the secondary water tank 14 through a communication hole 15; the secondary water tank 14 is structured like a radiator for reducing the temperature of the cooling water to a lower level.

The invention determines the flow of the water pump 1 according to the cooling water flow requirement of the engine and the heat load requirements of the generator controller 3 and the generator 4. The water pump 1 can be mechanically driven by an engine or can adopt an electric water pump.
The cooling water at the outlet of the water pump 1 firstly passes through the generator controller 3 and the generator 4, the pipe diameter of the tee joint 2 flowing through the generator controller 3 and the one-way valve 5 is determined according to the ratio of the water flow of the generator 4 and the generator controller 3 to the water flow of the engine, and the opening pressure of the one-way valve 5 is equal to or slightly greater than the pressure loss of the generator controller 3 and the generator 4.
